OTTO H. MARX, OF LAVERNIA, TEXAS.
SULKY-PLOW.Specification of Letters Patent.
Patented Aug. 18, 1908.
Application filed February 12, 1908. Serial No. 415,613,
To all whom it may concern:
Be it known that I, OTTO H. MARX, a citi-
zen of the United States, residing at Laver-
nia, in the county of Wilson and State of
5 Texas, have invented certain new and useful
Improvements in Sulky-Plows, of which the
following is a specification.
This invention relates to new and useful
improvements in draft eveners and it has
10 more particular reference to a three-horse
evener for sulky plows.
Ordinarily, in three-horse eveners in secur-
ing a straight and easy draft the central tree
is in such propinquity to the central pole that
15 the middle horse constantly rubs against the
said pole. The present invention therefore
contemplates as its primary object, while se-
curing a straight and easy draft to provide a
novel and inexpensive connection for offset-
20 ting the projecting portion of the pole from
that part which extends longitudinally of the
plow frame.
The details of construction will appear in
the course of the following description, in
25 which reference is had to the accompanying
drawings forming a part of this specification,
like characters of reference designating simi-
lar parts throughout the several views,
wherein:-
30 Figure 1 is a top plan view showing an
evener construction in which the present in-
vention is embodied. Fig. 2 is a side eleva-
tion of the same, and Fig. 3 is a detailed per-
spective view of the connection above re-
35 ferred to.
A conventional sulky plow A is shown in
the accompanying drawings which plow is
equipped with the beam B, to which is-se-
cured the pole C, made in sections 1 and 2, the
40 section 1 being secured to the beam. B, and
the section 2 being secured to the end of the
section 1 by the offsetting clip 3.
The draft evener D is connected to the
section 1 by a clevis 4, which includes a part
45 5 secured to section 1, and having its ears 6
formed with vertical series of apertures 7,
and a part 8 having ears 9, adjustably secured
to the ears 6 by pins 10 engaged through the
apertures 7. The part 8, disposed in a hori-
50 zontal plane has a series of apertures 11, to
allow of the adjustable connection therewith I
of a coupling hook 12 which engages a rear-
wardly extending loop 13 carried centrally of
a main evener beam 14. From. the ends of the
55 beam 14, auxiliary evener beams 15 arepivotally hung, the connections of the beams
15 being closely adjacent to the outer ends of
the latter. The inner ends of the beams 15
are connected by a one-piece clip 16, which
is pivoted to said inner ends so as to allow of 60
the beams 15 having the necessary play in
evening the draft. Swingle trees 17 are pivot-
ally hung from the outer ends of the beams
15, and a centrally located swingle tree 18 is
hung from the clip 16. 65
The clip 3, in order to offset the section 2
from the section 1 has its body portion ex-
tended along a diagonal axis and at its lower
end is formed with a pair of rearwardly ex-
tending spaced lugs 19 and at its upper end 73
with a pair of forwardly extending spaced
lugs 20. The ends of the sections 1 and 2
are received between the respective lugs 19
and 20 and are fastened in this relation by
bolt and nut fastenings 21 and 22. It will 75
thus be seen that the diagonal form of the
body of the clip offsets the section 2 above
and at one side of the section 1 so that the
same is closely adjacent one end of the tree
18 and at a material distance from the center sc
thereof. Hence, all liability of the central
horse rubbing against section 2 which car-
ries the neck yoke centers, is positively elimi-
nated.
The invention is simple in its structural s
details, inexpensive to manufacture and
practical and efficient in use.
Having fully described my invention I
claim:
1. In a wheeled structure in combination o
with a beam, a pole composed of two sec-
tions, one of said sections being secured to
said beam, a clip composed of two pairs of
spaced horizontal lugs, said pairs of lugs be-
ing disposed in different horizontal and ver- 05
tical planes, and a body connecting the inner
ends of each pair of lugs, said section being
secured to one of said pairs of lugs, the other
section being secured to the other of said
pairs of lugs, a three horse draft evener in- 100
eluding three swingle trees, and means to
secure said evener to the first named section
so that said evener may have vertical and
horizontal adjustment with respect to said
first named section. 105
2. In a wheeled structure in combination,
a beam, a pole secured thereto and compris-
ing a section secured to the beam, and a sec-
ond section forwardly projecting therebe-
yond, a clip connecting the sections and off- 110No. 896,650.
